Task Coach is an extremely powerful task management application that currently runs on Windows, Linux, Mac OS and iPhone. I'd really like to see it ported to Maemo, and I think doing so would give Maemo a more powerful task manager than any of those currently available.

I've submitted a feature request to their team for them to consider porting Task Coach to Maemo. If you'd like to see it ported, you can vote here:

You can give it up to 3 votes.

On the other hand, if someone here would like to take up a porting effort, I'd be happy to help. Task Coach is Python Based.
